It completed but it's only giving me 1 .img file, and when I loaded it into mricro, it thinks the z dimension is 8000 (the number of slices total). It should give me 400 volumes (20 slices each). So I want image001.img, 002.img, and so on. How can I do this? Do I have to rename the files differently?

sorry, also add -ic 0 0 0

You can try specifying the input geometry with something like -iis 1 -ijs 1 -iks 1 -iid 1 0 0 -ijd 0 1 0 -ikd 0 0 1
this is undoubtedly wrong, but should allow the command to finish

It got a little further (with "-it ge" and without any --in_type flag), but I get this error:

sorry, it's a little finicky, I think it is looking for a %03d format, meaning I.001 for slices numbers less than 1000, and I.1001 for greater

I renamed them all to "I.1, I.2, ..., I.8000" (there are 8000 images total), and I got the same error messages. (With the "-it ge" option, it is still looking for the old filename, it seems)
